Philips HF-R 258 Electronic Ballast for Fluorescent Lamps

The Philips HF-R 258 is a high-frequency electronic ballast specifically engineered for the reliable and efficient operation of TL-D fluorescent lamps. Designed to support two 58W lamps, this ballast ensures consistent performance across a standard 220-240V power supply. By utilizing high-frequency technology, it provides flicker-free ignition and smooth dimming capabilities, making it a professional-grade component for modern lighting infrastructures.

Advantages

This electronic ballast offers significant improvements over traditional magnetic ballasts by reducing energy consumption and extending the operational lifespan of connected fluorescent lamps. The integrated 1-10V dimming interface allows for precise light level control, enabling users to adjust brightness according to specific environmental needs. Furthermore, the high-frequency operation eliminates visible flickering and audible noise, contributing to a more comfortable and productive lighting environment.

Suitable for

• Office lighting systems requiring dimmable controls
• Educational facilities and classrooms
• Commercial retail spaces
• Industrial lighting setups using TL-D fluorescent tubes

When it may not be suitable

This ballast is not intended for use with LED lighting systems or non-fluorescent light sources. It is specifically calibrated for TL-D fluorescent lamps and may not function correctly with other lamp types or wattages outside of its specified range.

Key specifications

• Input voltage: 220-240 V
• Frequency: 50/60 Hz
• Lamp compatibility: 2x58W TL-D fluorescent lamps
• Control interface: 1-10V dimmable
• Technology: High-frequency electronic

How to use

Installation should be performed by a qualified electrician in accordance with local electrical safety standards. The ballast must be wired to the fluorescent lamps and the 1-10V control signal according to the wiring diagram printed on the device casing. Ensure that the power supply is disconnected before beginning the installation process. Once correctly wired, the ballast will automatically manage the ignition and dimming functions based on the input signal received.

What to consider before purchase

• Verify that your existing fluorescent lamps are compatible with the 58W TL-D specification
• Ensure your lighting control system supports a 1-10V dimming interface
• Check the physical dimensions of the ballast to ensure it fits within your existing luminaire housing

Usage recommendations

For optimal performance and safety, always ensure that the ballast is installed in a well-ventilated luminaire to prevent overheating. Regularly inspect the lamp connections to maintain consistent electrical contact and prevent premature failure of the ballast or the lamps.
